User I/O Xrm Io146 - Rocket - Alpha Data ADM-XRC-II Pro Hardware Manual

11 User I/O XRM IO146 – Rocket
The XRM-IO146 - Rocket is based on the XRM-IO146 module but has bank 4 on the mictor used to bring out
the 7 MGT channels available on the ADM-XP boards. The termination scheme on the differential and single
ended IO has also been changed from the standard XRM-IO146 allowing termination for LVPECL and BLVDS
standards to be implemented on the XRM module rather than externally.
The default manufacturing option is Rs=0R and Rt not fitted. Other options are available. Rs can be used to
provide series damping in point to point applications but for LVDS is 0R. Rt is required for LVDS inputs to
provide the termination voltage from the line current.
